Every time I send a request in planning mode, it fails with an error in the planning tool. The plan docs I had created before upgrading disappeared and could not be recreated.
Steps to Reproduce
upgrade to 2.1.0
see all your plans evaporate like Thanos victims
try to create new plans
witness tool error
cry
You can obviously still plan in agent mode with a markdown doc, but it is much more likely to haul off and start building things even if instructed not to. When combined with Custom Modes missing in Cursor 2.1.0 (VSCode 1.105.1) - #5 by tiz.io, this prevents any sort of read-only planning setup.
Operating System
Windows 10/11
Current Cursor Version (Menu → About Cursor → Copy)
Hey, thanks for the detailed report. It looks like this is a regression in 2.1.0.
Please share:

This will help the team investigate. Also, please try updating to version 2.1.6, as this may already be fixed there. Let me know if the issue still persists after updating.
I want to add that when this happens I can reload the window to recover from it. It just recreates the plan from the scratch following previous context.
this is annoying and hard to pin point on the reason it is doing it. It seems like alot of people experiencing it, but also it is working for some. There is a trigger that causes it for sure. My flow thats failing is already had a plan generated today and I was going over it replanning to align with my vision exactly, but it failed during editing a plan so that should be some clue. The plan might be working if you are starting fresh, so this could be something mid-flow after you have generated a plan already
I restarted all cursor instances and relaunched curosr switched from auto to composer 1 and it worked. if you face this, just restart all you cursor instances or restart the machine and hope it works. it resolved itself, thats how much I can provide
2.1.46
I always encounter this error when the cursor asks for answers to a question.
If I close the window and type the answers myself in the chat, everything works.
Under the hood, are we wasting tokens having to do this workaround? I’m worried this is increasing our costs when I’m constantly having to remake plans or instruct the agent to work around this issue.

The problem: I used ~100k tokens with opus 4.5, generated a plan, tried to suggest edits to the plan (another ~50k tokens or so), the edits failed, I tried to tell it to generate a new plan with the edits but that failed as well, and now I’m in a state where ~200-300k tokens are wasted because the agent couldn’t create the new plan properly. The newly generated plan had a bunch of missing things from the first plan.
It’s completely unusable like this. And wasting $$.
Also curious here about token wastage. This seems like it has the potential to cause a lot of token usage on our side to work around the plan feature here.
